Mobilgard™ M30 Series diesel engine oils
These extra-high-performance trunk piston engine oils are formulated using the latest additive detergent technology to help protect against deposits in piston undercrowns, crankcases, ring belt and camshaft areas. Their outstanding residual fuel compatibility helps reduce sludge formation and enables excellent engine cleanliness.
Our range of 30, 40 and 50 TBN MobilGard™ lubricants are designed for use in the most severe residual medium-speed diesel marine applications, and can help:
- Extend the life of critical wear surfaces
- Optimise component life
- Minimise lubricant consumption
- Reduce maintenance and operational costs

Features and Benefits
Mobilgard M30 Series oils have high performance thermal and oxidation stability. They have excellent TBN retention and resistance to viscosity increases over long operating periods. They also promote a high level of engine cleanliness with protection against wear. Compared to other medium speed engine oils, they have excellent lube/fuel compatibility and separate easily from water.
When used as recommended, Mobilgard M30 Series oils provide the following benefits:
|Features||Advantages and Potential Benefits|
|Excellent thermal and oxidation stability||Reduced deposits in piston undercrown and ring belt areas|
|Improved anti-wear properties||Extends the life of critical wear surfaces|
|Advanced detergency/dispersancy||Clean camshaft and crankcase spaces|
|Outstanding rust and corrosion properties||Protects wear surfaces from water and acidic corrosion|
|High Residual Fuel Compatibility||Reduced sludge formation, longer oil life, cleaner engines|
|Low volatility base stocks||Reduced lubricant consumption|
|Excellent TBN Reserve and Retention||Combats fuel/combustion related corrosion and deposits|
Mobilgard M30 Series oils can be used in most medium-speed trunk piston engine applications. They are recommended for use in main propulsion and auxiliary engines on deep-sea vessels; in main propulsion engines on coastal and river ships; and in stationary power plants. This new Series of oils is the result of an extensive research and development program, incorporating ExxonMobil's patented DAC (Detecting Aspahltene Contamination) Test.
Mobilgard M30 Series oils are designed to meet the needs of engines operating on heavy fuel. They are recommended for use in the latest model medium speed diesel engines and are especially beneficial in engines having low crankcase oil consumption or operating with low cylinder liner temperatures. Relatively high alkalinity reserves in these oils provide excellent protection in neutralising the strong acids resulting from the use of high sulphur fuels that find access to the crankcase to promote oil degradation and ring, cylinder, and bearing corrosion.
